全球冰川灾害与冰碛湖溃决洪水清单（1901-2020）

持续的全球变暖和冰冻圈退化正在引起人们对适应山区环境不稳定的关注。近几十年来，与冰川有关的斜坡崩塌，如冰崩、冰川上的岩崩，已被频繁记录。在这项研究中，我们建立了一个与冰川有关的滑塌的全球清单，以研究它们的分布、趋势、断裂以及与气候变化的关系。在1901-2019年期间，共记录了737起与冰川相关的滑塌事件，包括156次冰崩，89次冰-岩崩，26次冰川滑塌，以及466次冰川上岩崩。西北太平洋地区有记录的案例最多（N=440，60%），其中以冰川上岩崩最为主要。此外，整合与完善了目前公布的地区或全球性质的冰湖溃决洪水清单，并单独分离出了冰碛湖溃决洪水事件。1901-2020年间共统计到380起冰碛湖溃决洪水事件，是目前最为完善的全球范围内的清单。

Ongoing global warming and cryosphere degradation have raised concerns regarding adaptation to the instability of mountainous environments. In recent decades, glacier-related slope failures such as ice avalanches and rock avalanches on glaciers have been frequently documented. In this study, we compiled a global inventory of glacier-related landslides to investigate their distribution, trends, rupture characteristics, and associations with climate change. A total of 737 glacier-related landslide events were recorded between 1901 and 2019, including 156 ice avalanches, 89 ice-rock avalanches, 26 glacier slumps, and 466 rock avalanches on glaciers. The North Pacific region has the largest number of documented cases (N=440, 60%), with rock avalanches on glaciers being the dominant type. Additionally, we integrated and improved currently published regional and global inventories of glacial lake outburst floods (GLOFs), and separately extracted moraine-dammed lake outburst flood events. A total of 380 moraine-dammed lake outburst flood events were recorded between 1901 and 2020, making this the most comprehensive global inventory currently available.
